Suggest Treatment For Headaches

Hi There, I've been having headaches for over a week now and thought it could have been part of a flu bug, but I have no other symptoms. It feels like it's all over my head sometimes and makes me feel like i just need to lay down. Tylenol, Advil and Motrin aren't working. I've only taken a few a day, not every four hours though. Any suggestions? Thanks!
